I can't tell you that there's no logic to it. They want to attract a NEW audience to the old franchise. That's why game has cut scenes and many features are simplified. To make it easier for people who are not familiar with BG and DnD to understand. If they wanted to please old BG fans, they wouldn't even think about the cutscenes, obviously. Many new players have not even heard about such a game as BG, they literally learned about its existence thanks to BG3. Imagine, it's been 20+ years. People who are now 20-25 years old may never have heard of this game, because it is very old. Even if they heard about it, they probably weren't playing. This has its own logic. You were attracted by the name, and others were attracted by everything else.
In theory, Larian can revive franchise, but, of course, not for you, but for a new generation of players.
I have no idea why you're saying that old BG fans wouldn't like cutscenes. Unless you're arguing that old BG fans want only the mechanics and game features that were in BG 1&2 and no more, which is such an incredible strawman that there's not much more to say.
Reviving the franchise isn't mutually exclusive with making a game that's true to D&D 5e, and the presence of cutscenes even more so isn't mutually exclusive with D&D.
